    Change default exception in wait_until_true

    By default, wait_until_true uses default exception from eventlet which
    is eventlet.TimeoutError. This class is not subclass of Exception but
    BaseException. In case wait_until_true times out in any test, the whole
    test executor worker is stopped leaving scheduled tests not executed.
    This patch replaces eventlet.TimeoutError with new WaitTimeout
    exception, that inherits from Exception and thus won't break execution
    of other test cases in case it's raised.
